Applications MATV installations where it is necessary to generate an analogue Cff channel with mono sound from the audio and video signal from equipment with mono or stereo sound.

Mechanical accessories for the installation of the antennas 5 6 and dishes. Each module permits the amplification and equalisation of two to four channels. In equipment with F-type connectors, it is necessary to use insulated loads. The audio input can be mono, stereo or dual by selecting the audio mode of the modulator by means of the programmer. The antenna preamplifier is used when the signal level is very low.

After that you need to determine the operational rate group of the lifting device according to FEM 9. Catalogue Gianni Ferrari offers the advanced engines on the market: It has one inputs to amplify the signal coming from all the modulators of the installation, and a mutliplexing input for the rest of the channels of the installation.

The AM allows only the low and high channels amplification. Essential features of this equipment are the high carrier to noise ratio together with a alcd reduced spurious level in the band. Model FU is used for installations in cascade, and to supply power to amplifiers and active multiswitches. With a tempered steel nail. Fixed to the mast by means of a polyamide clamp. They have several inputs to amplify and combine the signals from several antennas.


Telephony elements of connection and distribution for telephone installations. Cv addition, the specifications, measurement methods and publication of information regarding these products fully comply with the following non-obligatory norms: In this way, a perfect equalisation is obtained of all the channels received. Its use achieves the best possible signal to noise ratio. The noise level is extremely low in order to amplify the signals without losing quality.

It is necessary to use SAT amplifiers to amplify all the satellite signals.

Characteristics 4 Shielded zamak chassis, covered 1122 an ABS plastic box for outdoor use. Applications TV reception in places where there is no TV installation, such as camping sites or in cars or caravans. The AM and AM are available in kit format see page 53 and following pages.

Distribution in cascade from the first multiswitch, with 5 coaxial cables between multiswitches and a single coaxial cable to each TV outlet.

From the simplest equipment for individual installations to cascadable equipment for large installations. The HT tool must be used to connect the pairs. CA The CA amplifier is available in other preamplifier power voltages see page Characteristics FM Robust antenna with great resistance to both sun and saltpetre.

Permits the independent reading of both sides of the installation. The built-in power supply unit can feed up to five preamplifiers and a LNB automatically. Used to feed intermediate active multiswitches starting from only one amplifier in the head-end.


Shielded zamak chassis with plastic supports. Alternate filters should be used if two filters are adjusted to the same frequency.

Permits reduction of the level of a polarity when it is too strong to prevent interference with the other polarities see page Base for dish stand for embedding. They are fed through the coaxial cable from a power supply unit installed inside the building. Zamak F-type connectors which form part of splitter chassis. Especially appropriate as an apartment amplifier in cable TV networks or in community installations where the interband bands are used.

TV standard tables and identification of channels. It allows the treatment of any combination of channels, including adjacent channels with monochannel or multichannel treatment. Characteristics Made from round galvanised iron tube.

Applications Designed to enlarge analogue and digital terrestrial TV installations within a house. Multiplexing and diplexing bridge with high-speed male F-type connector, to combine the signal of the modules or for the distribution of the signal from one antenna to several modules.

Switch to supply power to preamplifiers with protection against short circuits. The different sections of the mast are assembled by inserting the upper part of the mast into the lower part of the other section, securing them with an M6 screw which passes through the tubes. Characteristics Transmission of the remote control via radio, on the 2. A SAT amplifier must be used to amplify all the satellite signals.

Each band has a gain control and a variable equaliser.
